Power steering pump wiring question
 

I'm using a ZF power steering pump from a MINIto drive a Sweet servo connected to a Sweet slave cylinder in a GT2 track car.
The power connections on the pump are obvious, but the additional plug on the pump has no labeling, nor do I have a schematic for a MINI.
What do we need to do to get the pump to run?
Thanks in advance for any help on this matter.
